Download mulitple SharePoint Attachment and make One PPT
12/18/2015
Some good old farm code after a long time.
The requirement is to let the user select a date range and
then ask SharePoint to download a single compiled ppt from a list. This ppt is a compiled ppt from attachments
of the slides from each list items.
The items are filtered based on Creation Date and Code uses
the Open xml to generate the ppt
Here are the steps to run the code... The code files can be
downloaded from here
1. Download and
install Open xml from here.
2. To your wsp Farm
solution add the CombioneSlidesToPpt.aspx file. The Page load, reads the incoming query parameters,
downloads the list items and then generates one single ppt.
This ppt is generated by taking a copy of the existing
template ppt and then adding the slides to this ppt.
The template is kept under the path as listed in the C# code. Make sure you already have the folder and
path correctly set in your environment
3. From the client
side, I have a content editor web part which points to my index.html file. I
put this file in Document library (you can put it anywhere in any doc lib as
long as you modify the link in CEWP).
4. The index file is simply an html file which renders date
time field as well as the button to download the ppt. I am using Angular to capture the date ranges
and generate the link. In your case, you can directly set these in url and call
the page via browser to test
hope his helps. Any problem
in replicating the code gimme a ping on twitter @techAkki
